Leonids Meteor Shower Peaks Nov. 17, 18


The Leonids is an average shower, producing up to 15 meteors per hour at its peak. This shower is unique in that it has a cyclonic peak about every 33 years where hundreds of meteors per hour can be seen. That last of these occurred in 2001. The Leonids is produced by dust grains left behind by comet Tempel-Tuttle, which was discovered in 1865. The shower runs annually from November 6-30. It peaks this year on the night of the 17th and morning of the 18th.


The Leonid meteor shower happens every year in November, when Earth’s orbit crosses the orbit of Comet Tempel-Tuttle. The comet makes its way around the sun every 33.3 years, leaving a trail of dust rubble in its wake.

When Earth’s orbit crosses this trail of debris, pieces of the comet fall toward the planet’s surface. Drag, or air resistance, in Earth’s atmosphere cause the comet’s crumbs to heat up and ignite into burning balls of fire called meteors.

These comet crumbs are usually the size of a grain of sand or a pea, so they tend to burn up entirely before striking Earth’s surface. Meteors that survive the whole journey to the ground are called meteorites. But the Leonid meteor shower likely won’t deliver any meteorites.
